Click the Functions tab of the Variables toolbox to see the values used in the function.

You can define this function in these ways:

  • Modify the edit line at the bottom of the Functions tab.   (Use your keyboard arrow keys to move through the whole function.)
  • Modify the function interactively using "handles".  In the drawing window, click the function to select it.  Click and drag it and a circle appears on the curve.  This handle represents one of the variables in the equation.  You can click and drag a handle around the drawing to change the curve.  Click and drag another place on the curve and another moveable handle appears  if there is another function variable in the equation. In the general function in this example we have 5 possible handles: f(a), f(b), f(k), f(u), and f(v).
